DANIEL F. FEBNEY, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR T0 GRAND RAPIDS SCHOOL EQUIPMENT 00., OF GRAND RAPIDS, MICHIGAN.

VISE.

Application filed January 14, 1916.

Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Vises, of which the following is a specification. v

This invention relates to improvements in Vises.

The main objects of this invention are: First,'to provide in a vise an improved adjusting mechanism. Second, to provide in a vise an improved adjusting mechanism which is capable of very rapid and easy manipulation. Third, to provide an improved device having these advantages which is comparatively simple and compact in structure and not likely to get out of repair in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of a structure embodying the features of my invention. Fig. II is an inverted view thereof with the bottom plate of the frame removed. Fig. III is a vertical longitudinal section on a line corresponding to line 3-3 of Figs. II, IV and V, the screw being Shown in full lines. Fig. IV is an enlarged transverse section on a line corresponding to line 4-t of Figs. II and III. Fig. V is a transverse section on a line corresponding to line 5-5 of Figs. II and III. Fig. VI is a top perspective view of the split nut shiftmg member. Fig. VII is a perspective view of one of the split nut members. Fig. VIII is a detail transverse section on a line corresponding to line 88 of Fig. III.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the frame 1 is Specification of Letters Patent.

adapted to be bolted on the under side of a bench or support to support the vise jaw 2 in operative relation to the edge of the bench or support. The frame is provided with groove-like ways 3 for the slide 41 of the jaw. The adjusting screw 5 is journaled in the jaw at 6 and is provided with a suitable handle 7. The frame is shaped to receive the screw below the jaw slide 4.

A pair of split nut members 8 is provided to coact with the screw, the members 8 being oppositely disposed so that when adjusted to one position they engage the screw so that the jaw is adjusted by the turning of the screw and when adjusted to another position they free the screw so that the jaw slide may be moved freely. These jaw members 8 are provided with bar-like slides 9 disposed transversely of the frame. The side members 10 of the frame are recessed or notched at 11 to receive and support the slides, the slides beingarranged side by side so that their ends project through these notches as shown in Figs. I, II, and IV. The nut sections are offset on their slides so that they are opposite and when in screw engaging position form substantially a complete nut. The slides 9 are provided with cam lugs 12 which are engaged by the shifting member 13 disposed below the slides 9 and supported for sliding movement longi- 'tudinally thereof by the bottom plate 14 of the frame (see Figs. III and IV).

The shifting member 18 is plate-like in form and is provided with oppositely disposed inclined slots 15 which receive the lugs 12 so that when the plate is shifted longitudinally the slides 9 are shifted transversely of the screws to engage and disengage the nut members. The shifting member 13 is provided with a tooth-like lug 16 engaging a spiral groove 17 in the actuating member 18. The actuating member 18 is rotatably mounted upon the screw but is supported against longitudinal movement thereon. The actuating member 18 is provided with a friction block 20 bearing on the screw, so that when the screw is rotated the actuating member tends to rotate therewith unless prevented by engagement with stops, the housing or extension 21 on the actuating member, in the structure illustrated, being adapted to engage the jaw slide, thus limiting the rotative movement of the actuating member. The friction block is pressed against the screw by the spring 22 held in its housing by the pin 23. The movement of the actuating memher is such that when the nut members are in disengaging position and the screw is turned in the jaw clamping direction the shifting member is actuated sufiiciently to engage the nut members. Owing, however, to the friction connection for the actuating member to the screw continued movement of the screw is permitted to clamp the jaw. The reverse movement of the screw will rotate the actuating member to its opposite position and this acting on the shifting member 13 disengages the nut members permitting free longitudinal adjustment of the screw and with it the vise jaw. The aw is preferably provided with a sliding dog 24 which may be adjusted to project above the surface of the bench as at 25, indicated by dotted lines in Fig. III.

With the parts thus arranged, the vise may be very quickly and easily adjusted to clamp or release work. The structure is strong and durable and at the same time comparatively simple and compact.

I have illustrated and described my improved vise in an embodiment which I have found to be very satisfactory. I have not attempted to illustrate or describe various modifications which I contemplate, as I believe the disclosure made will enable those skilled in the art to which this invention relates to embody or adapt the same as taste or conditions may dictate. I desire, however, to be understood as claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
